Abstract
A composite surfacing method is technically characterized in that firstly, a bare electrode is welded by 500A-600A current; and secondarily, welding wires are used for surfacing after the bare electrode is welded to a certain thickness, the current is 380 A-450 A, the thickness is 25-40 mm, the bare electrode adopts a thick bare electrode, the diameter of the bare electrode ranges from 12 mm to 16 mm, and the bare electrode is manually welded. With the adoption of the technical scheme, the permeability of surfacing is increased by 2.5 times, an alloy material can be well bonded with a base material after welded, the welding wires are used for surfacing after the material is welded to a certain thickness so as to guarantee the attractiveness of the shape, the automatic surfacing cost by the welding wire is high, the surfacing welding electrode manufacturing cost by using the bare electrode is low, the product manufacturing cost is effectively reduced by one fourth, the dropping phenomenon of a welding material is reduced, and the welding quality is stable.
Description
Technical field
The present invention relates to welding method technical field, particularly a kind of combined type welding method.
Background technology
Solder technology is mainly used on metal mother metal, conventional have an arc welding, argon arc welding, CO2 protects weldering, oxygen-acetylene welding, laser weld, electroslag pressure weldings etc. are multiple, existing each manufacturing enterprise adopts the process of welding wire automatic surfacing mostly, the product of this kind of process built-up welding, but although in forming welding process because welding wire is thin, electric current can not be excessive, that foolish rear resurfacing welding material can not be well affine with mother metal, floating put forth effort bad, therefore, in equipment use procedure, alloy material very easily comes off, in order to solve this difficult problem, some enterprises adopt the method for the excessive layer of welding to solve, but effect is also unsatisfactory.
Summary of the invention
In order to address the above problem, the invention provides semi-automatic wear resistance electrode built-up welder.
A combined type welding method, is characterized in that: the first step, bare electrode is carried out to welding with the electric current of 500A-600A, and second step, welding is used welding wire built-up welding again to certain thickness.
Further, described electric current is 380A-450A
Further, described thickness is 25-40 millimeter.
Further, described bare electrode is thick bare electrode.
Further, the diameter of described thick bare electrode is 12-16 millimeter.
Further, described bare electrode is manual welding.
Advantage of the present invention:
1, directly with thick bare electrode, carry out high-power welding, make the permeability of built-up welding strengthen 2.5 times, guaranteed after alloy material welding well bonding with mother metal;
2, welding uses welding wire built-up welding attractive in appearance to guarantee moulding after certain thickness again;
3, reduced the obscission of wlding;
4, bare electrode cost of manufacture is low, also effectively reduces production cost;
5, welding steady quality.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, following examples, are further elaborated to the present invention; Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1
A combined type welding method, the first step, carries out welding by bare electrode with the electric current of 500A-600A, second step, welding is used welding wire built-up welding again to certain thickness.
Described power is 380A-450A
Described thickness is 25-40 millimeter.
Described bare electrode is thick bare electrode, and the diameter of thick bare electrode is 12-16 millimeter.
Described bare electrode is manual welding.
Directly use thick bare electrode, high-power welding, makes the permeability of built-up welding strengthen 2.5 times, has guaranteed after alloy material welding well bondingly with mother metal, and welding is to attractive in appearance to guarantee moulding with welding wire built-up welding again after certain thickness.
Welding wire automatic surfacing cost is high, low by bare electrode surfacing welding cost of manufacture, effectively reduces production cost, reduces cost of manufacture 1/4, has reduced the obscission of wlding, welding steady quality.
